IMPROVEMENT IN PUMPS.

The Schedule referred to in these Letters Patent and making part of the-same To all whom t't-mafy concern:A

Be it known that I, WALTER F. JONES, of Syracuse, in the county of Onondaga, in the State of New York, have invented a new audimproved Mode ot' Elerating or Forcing lVater; and I do hereby declare that4 the following is a full and exact description thereot, reterence'beiug had to tlieaccompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in elevating or forcing water, by means, of a plunger or shaft,tapered at the lower extremity in the form of a wedge or cone, and: put in the place of au ordinary piston-rod, in a common force-pump. 1

To enable others skilled in the art to make and use my invention, the I will proceedto describe its constructionV and operation.

I construct a hollow cylinder, as shown at A in the accompanying drawing, of iron, wood, or other metal, of diameter proportionately larger than that of my plunger, whiclris marked B in the drawing.

At the bottom, or near the bottom, on the side of the cylinder, I insert a valve, marked O, which opens within the cylinder, in order to enable the water to fdl the same when the lower point of the plunger is drawn up to thertop` or cap of the cylinder, which is marked D.

' At the bottom edge of this cylinder', I attach an escape-pipe, marked E, of any known ordinary form, in which there is a valve, marked F, opening within the escape-pipe, to prevent the water flowing back into the main cylinder.

The top and bottom of the cylinder are made of iron plates, aud rmly secured with bolts.

A hole is \made through the top plate, which is marked G, of diameter the saine as that of the plunger', through which the plunger is to pass into the cylinder, and penetrate nearly to its bottom.

'lhe hollougof the cylinder is to be from one to three inches'in diameter greater than that of the plunger,

and the plunger is to pass directly through the centre of' this hollow, so that it ma-y'not come nearer than oneor two inches (more, the better,) ofthe side ot' the cylinder.

"Ihis cylinder may be of auy required strength, length, and size, and is to` be wholly immersed in water.

The plunger, besides being, at its lower extremity, in a wedge or cone-form, should perfectly ll the hole-in the top plate, or, at that point, be surrounded with sufficient packing to prevent the water escaping therefrom, so that when the plunger is forced down, and penetrates the waterin the cylinder, the water tlows into the escape-pipe.

The plunger is made of iron 0r`other metal. This form ot' plunger, first, acts upon the ,water on the principle of a wedge or inclined plane, and diminishes the power necessary to overcome the resistance in an ordinary force-pump; second, it displaces and forces a column of water (the size of the plunger) through the centre of the wa'ter in the cylinder, and but slightly disturbs the water at the sides. Thereby it avoids, or rather it does notproduce any friction 'at the sides of the cylinder, which is' crea-ted by a common piston-rod in an ordinary force-pump.

I ain aware that pumps have been constructed (and used) on the same principle as mine, but the plunger or piston of quite a different shape.

H aving thus fully described my invention,

What I claim as new, and desire to secure by Let-4 The piston or plunger` B, provided with a wedge or cone-shaped point, and used in combination with a. force-pump, substantially as shown and described.

WALTER F. JONES.
